Research shows that children experience a smoother transition into elementary school when there is coordination among schools, early childhood education programs, and families. The Early Childhood Community School Linkages Project (the Linkages project) supported three regions with a strong community school platform to improve the quality and continuity of practice across community school and e...

We analytically characterize the aggregate productivity loss from distortions in presence of sectoral production linkages and show key role input substitutability. analyze various forces behind non-monotonic effect substitutability on loss. then use second-order approximation to find that for moderate distortions, low reduces intermediate-input suppliers. Moreover, when elasticity substitution ...

2΄-5΄-linked RNAs play important roles in many biological systems. In addition, the mixture of 2΄-5΄ and 3΄-5΄ phosphodiester bonds have emerged as a plausible structural element in prebiotic RNAs. Toward our mechanistic studies of RNA folding and structures with heterogeneous backbones, we recently reported two crystal structures of a decamer RNA duplex containing two and six 2΄-5΄-linkages, s...

Cam-modulated linkages that can achieve superior kinematic performance as compared with pure linkages have been widely applied in a variety of automation machinery. The tolerance analysis and synthesis are thus quite essential in the design and manufacture of precision cam-modulated linkages. This paper presents comprehensive and systematic mathematical tools for dealingwith the tolerance analy...

Abstract: This study aims to analyze how the influence of infrastructure availability, socioeconomic conditions, and effect location on poverty levels. The descriptive analysis is used give a general description by using thematic charts maps. map analyzed spatial autocorrelation levels Moran Scatterplot Local Indicators Spatial Association (LISA) Map. results indicate existence linkages poverty...

in the light of the 2008 world development report, this paper revisits the impact of agriculture on overall economic growth, in the case of an oil producing country, using indices of intersectoral linkages. to this end, four input-output tables of iran’s economy are utilized. the results support the importance of the agricultural sector in stimulating the economic growth of iran, but also s...
